Description Janis Meybohm univentionstaff 2015-03-19 15:34:18 CET

Because "admin" is not permitted by username syntax, 90_postjoin/10admember fails when creating the domain admin. As this is done after the AD credentials have been verified, the message is very confusing for the user:

-- var/log/univention_setup.log
__MSG__:Einrichten des Administrator-Kontos...
19.03.15 10:23:47.242  MODULE      ( PROCESS ) : Prepare administrator account
19.03.15 10:23:47.475  MODULE      ( ERROR   ) : Account creation for admin failed
19.03.15 10:23:47.476  MODULE      ( ERROR   ) : udm users/user create output:
E: Invalid Syntax: User name: Username must only contain numbers, letters and dots, and may not be 'admin'!

__ERR__:Eine Verbindung zum AD-Server %s konnte nicht hergestellt werden. Bitte überprüfen Sie Benutzername und Passwort.

Happened here again while joining UCS into an AD domain: Ticket#2017070721000207

root@master441:~# udm users/user create --set username=admin --set lastname=Admin --set password=univention
E: Invalid Syntax: User name: Username must only contain numbers, letters and dots, and may not be 'admin'!
root@master441:~# s

We should allow admin as username.
